CMU study finds small battery PHEVs and gasoline hybrids the least-cost policy solution to reducing gasoline consumption

Green Car Congress

A 2011 paper by Michalek and colleagues found that strategies to promote adoption of HEVs and PHEVs with small battery packs offer more social benefits (i.e., air emissions and oil displacement benefits) in the near term per dollar spent than PHEVs and battery-electric vehicles (BEVs) with large battery packs providing longer electric range.
